Under Armour Performance started with a simple plan to make a superior T-shirt. The shirt needed to provide compression and wick away perspiration instead of absorb it. This shirt needed to work with your body by regulating temperature and enhancing performance. Under Armour is the innovator of performance apparel that all other brands are measured by. Their gear is engineered to keep you performing at the top of your game in all conditions. UA's technology and product assortment has grown far beyond that first T shirt to include a diverse product assortment for men, women and youth.
